PHANGS-ALMA: Star Formation at Molecular Cloud Scales
Abstract
ALMA has opened up the opportunity to map the distribution and properties of molecular gas on the scales of giant molecular clouds (GMCs) across the star-forming disks of nearby galaxies. The large project PHANGS-ALMA (Physics at High Angular resolution in Nearby GalaxieS) has imaged the CO(2-1) emission at high sensitivity at about 1" resolution from 74 massive, star-forming main-sequence galaxies to study how the molecular gas, its properties and its star-forming potential vary within and across the galaxies. Linking these observations to other global and local galaxy parameters such as stellar mass, star formation rate, local dynamics will allow us to gain new insights into the physics of the star formation process. The survey design, anticipated ALMA data products and first results will be presented.
